# Sourcegraph gradient

Gradients derived from Sourcegraph's published colour tokens (nominative use; no brand assets). Deterministic: the same values are served as `--brand-gradient*` in the brand's brand.css.

- Brand colors: https://brandsweets.com/colors/brands/sourcegraph-com · Brand page: https://brandsweets.com/b/sourcegraph-com

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #3fb950 0%, #d14d41 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#3fb950] to-[#d14d41]`
- Contrast (worst point): white 2.54:1 fail · black 4.85:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3fb950-d14d41?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.14 until the ink passes AA at the worst point (4.59:1).

- CSS: `linear-gradient(135deg in oklab, #5a7e5b 0%, #764841 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#5a7e5b] to-[#764841]`
- Contrast (worst point): white 4.59:1 AA · black 2.77:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.5a7e5b-764841?a=135

## Button / CTA

ΔL 0.08 top→bottom in the primary's hue (a lit surface, not a rainbow); hover L +0.03, active L −0.03. Black ink passes AA on the surface and both states (worst 6.36:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #4ec65d 0%, #2fac43 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#4ec65d] to-[#2fac43]`
- Contrast (worst point): white 2.20:1 fail · black 7.10:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.4ec65d-2fac43?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #59d066 0%, #3bb64d 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #43bc53 0%, #20a339 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #7ff589 0%, #3fb950 50%, #00800f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#7ff589] via-[#3fb950] to-[#00800f]`
- Contrast (worst point): white 1.37:1 fail · black 4.09:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.7ff589-3fb950-00800f?a=135&in=oklch&hue=shorter

## Analogous

Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #3fb950 0%, #9aa638 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#3fb950] to-[#9aa638]`
- Contrast (worst point): white 2.53:1 fail · black 7.87:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3fb950-9aa638?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 180° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #3fb950 0%, #e84ff0 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3fb950] to-[#e84ff0]`
- Contrast (worst point): white 2.53:1 fail · black 6.44:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3fb950-e84ff0?a=135&in=oklch&hue=shorter

## Triadic

Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #3fb950 0%, #759af0 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#3fb950] to-[#759af0]`
- Contrast (worst point): white 2.53:1 fail · black 7.61:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3fb950-759af0?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.54:1, black 4.85:1 AA */
  --brand-gradient: linear-gradient(135deg in oklab, #3fb950 0%, #d14d41 100%);
  /* hero — worst-case contrast: white 4.59:1 AA, black 2.77:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #5a7e5b 0%, #764841 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 2.20:1, black 7.10:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #4ec65d 0%, #2fac43 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #59d066 0%, #3bb64d 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #43bc53 0%, #20a339 100%);
  --brand-gradient-button-ink: #000000;
}
```

## Gradient maker

Every maker URL is the gradient's state: `/gradients/new/v1.<hex>-<hex>[_pos]?a=135&in=oklch&hue=shorter&e=soft&g=8`. Hand one to a human, let them refine, and read the link they return.

## Connect an agent

Point any MCP client at the BrandSweets gradients endpoint for the same engine and corpus:

- Endpoint: https://mcp.brandsweets.com/gradients/mcp
- Tools: `make_gradient` (2–5 colours → CSS with the interpolation space, Tailwind v4, SVG, PNG URL, DTCG token + the contrast/banding/gamut report), `brand_gradients` (brand slug or palette → brand gradient, hero, button, variants).
- Resource: `gradients://corpus` — the whole bundled corpus as JSON.
